Q20 / 110 · NTA Abhyas (NEET) 2020 · Physics · Units and Dimensions

Among the following quantities, the quantity whose dimension is independent of mass and length is

  • A
    Energy
  • B
    Thrust
  • C
    Momentum
  • Correct answer
    D
    Angular velocity

Solution

[Energy] =ML2T-2

[Thrust] =MLT-2

[Momentum] =MLT-1

[Angular velocity] =M0L0T-1

From the above it is clear that the dimensions of angular velocity is independent of mass and length.

Hence, the correct answer is option: 'D'.
